[Seaside] Seaside: children problem

[an organic]

Hi,

WAComponent subclass: #Site
    instanceVariableNames: 'head menu'
    classVariableNames: ''
    poolDictionaries: ''
    category: 'Pom'

children
    ^ Array with: self head with: self menu

initialize
    super initialize.

    head := Head new.
    menu := Menu2 new.

Is this info better?
But from menu2 in renderContentOn i call next Class WMenuItem which i want
use to render my items.
When i render items direct in menu2 component it works fine. But i want
learn render items in next component (because items are hierarchical
structure and WMenuItem can work recursively)

When i write render i think write in html to website ;).

I thought that problem is here: menu2 dont have dynamically created
WMenuItem in his children array. But i am not able to add it into this array
(children of menu2). When i change code renderContentOn of Menu2:

renderContentOn: html
    | temp |
    html
        unorderedList: [items do: [:item | temp := WMenuItem new. self
children: self children, temp. html div class: 'a'; with:  (temp kategorie:
item) ]]

i get this error:
Error: Instances of WMenuItem are not indexable
